5 Claims.

This invention relates to a sawing machine particularly adapted to cut iinished clay products such as building tile, brick, marble, gypsum and any equivalent.

It is generally aimed to improve, simplify and render more durable, a machine of this character and to provide a novel means for supporting a deck carrying a saw and operating mechanism; a construction wherein such deck is adjustable laterally, and a construction wherein the deck, saw and associated parts are adjustable vertically as -a unit, and a construction wherein the support of the deck is augmented by engagement with parts which in turn are in coacting relation with resilient spring means.

The more specific objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawings illustrating an operative embodiment.

In said drawings:

Figure 1 is a view in side elevation of .the improved sawing machine;

Figure 2 is a plan view of such sawing Inachine;

Figure 3 is a vertical sectional View taken substantially on the plane of line 3--3 of Figure 2;

Figure 4 is .a cross section taken on the line 4 3 of Figure 2, and

Figure 5 is a fragmentary rear elevation.

Referring specically to the drawings wherein like reference characters designate like or similar parts, a skeleton table is provided as at l having top rails i I in parallelism for engagement by wheels or rollers i2 of a rolling table I3, which carries the article or product to be cut as suggested at I4 and particularly finished clay products such as building tile, brick, marble, gypsum and any equivalent. Such skeleton frame I0 further includes hollow posts l one at each corner.

Vertically slidable in two of such posts I5 are rods I5 which are connected by a crossbar Il to form a frame and which frame is adjustable to various heights since a Ibeveled gear I8 has a hub I9 journaled on the bar Il and which has a bore in screw threaded engagement at with a rod 2i whose lower end may be pointed as at 22 and journaled in a bearing or support 23 mounted by a cross member 24 at the bases of two of the posts I5. Enmeshed with the beveled gear I8 is a beveled gear wheel 25 which is keyed to a rotatable shaft 25, journaled at suitable points on the frame I 0, and which is operable through the medium of a hand wheel 2l, preferably equipped with a crank 28.

The saw mounting frame has rearwardly eX- tending angle brackets 23, welded or otherwise fastened on to `the top of adjacent rods I6. Said brackets 23 mount screw studs Sii which pass through vertical fianges .thereof and on opposite 'sides of which 'they are engaged by lock nuts 30. The inner extremities of the studs 30 are pointed or tapered and removably extend into similarly shaped sockets 3i of a cross roll 32. This cross roll 32 may be readily removed upon loosening the studs 35, as will be understood. Laterally slidable on the cross roll 32 is a sleeve 33, of any suitable length, which is adapted to be clamped to the cross roll as by means of set screws 3d. Fas-tened to the cross roll is a deck 35 which mounts an electric motor 36 and journaled in any suitable manner, a shaft 3l which drives a saw 38, operatively geared .to rthe motor 33, for instance by means of a belt drive 39. The connection between the sleeve 33 and deck 35 is preferably a detachable one and may consist of lugs 43 rising from the tube 33 into openings 4I of the deck.

On opposite sides of the cross roll 32, the deck 35 rests on rest members or supports 42 and 43, similar in shape. Vertical rods 4S in the form of bolts pass upwardly through the rest members 42 and horizontal flanges of the brackets 29, having heads 45 at their lower ends and wing nuts 45 adjustable on their upper ends. Washers 4l and 48 engage the head 65 and nut 46 and expansive coil springs 43 surround the rods 44 engaging the washers 4l at one end and the rest members 42 at the other end. Also, coil springs 50 surround the rods 44 engaging the brackets 29 at one end and the washers 43 at the other end.

V-shaped brackets 5i are connected at the upper ends of the same rods I5 as the brackets 29 and they extend forwardly therefrom. Bolts 52 extend through the rest members 43 and brackets 5| having heads 53 at their lower ends and nuts 54 at their upper ends adjustable on screw threads of the rods. Said heads and nuts are abutted by washers 55 and 56. Expensive coil springs 5l surround the rods 52, abutting the washers 55 at one end and the rest members 43 at the other end. Similar coil springs 53, surround the rods 52, abutting the brackets 5I at one end and the washers 55 at the other end. It will be realized that the tension of the springs 49, 50, 51 and 58 may be regulated through the adjustment of the nuts 46 and 5i. A guard or hood 59 is provided over the saw 33 which will automatically catch dust and cuttings. A tank for applying water alt the Zone of cutting is designated 60 and suitably supported on the frame Il), having an adjustable outlet nozzle 6I with the flow under control of a valve 62.

Attention is called to the fact that there is no side play or twist of the saw blade and that the latter is laterally adjustable through the adjustment of the sleeve 33 laterally on the cross roll or rocker 32, it being clear that the sleeve 33 may be of any desired length according to the amplitude of adjustment desired.

Particular attention is called to the fact that the saw and al1 parts which adjust it vertically and drive it are adjustable as a unit to any desired height through the operation of the crank 28. In View of the fact that thedeck 35 and the saw 33 simply rest on the members 42 and 43,

that the deck and saw may be moved on the axis f of the rocker 32 and the saw disposed in engagement with the work I4, with the tension of the springs such as to pull the saw downwardly into the work as the cutting progresses, .the tension of such springs being readily regulable as previously described.

Various changes may be resorted to provided they fall within the spirit and scope of the nvention.

I claim as my invention: Y

1. In a machine of the class described, a deck, sawing mechanism carried by said deck, means mounting the deck for pivotal movement including a frame on which the deck rests on opposite sides of its pivotal axis, and resilient means associated with the deck above the same on opposite sides of its pivotal axis mounting the deck in normal position and arranged for tensioning through pivoting of the deck so that the saw will be subject to such tensioning.

2. In a machine of the class described, a deck, sawing mechanism carried by said deck, means mounting the deck for pivotal movement, resilient means associated with the deck on opposite sides of its pivotal axis mounting the deck in normal position and arranged for tensioning through pivoting of the deck so that the saw will be subject to such tensioning, mounting means for the deck and spring means, and a device operable to elevate the mounting means, deck, spring means and sawing mechanism as a unit.

3. In a machine o-i the class described, a deck, sawing mechanism carried by said deck, means mounting the deck for pivotal movement, means associated with the deck arranged for tensioning through pivoting of the deck so that the saw Will be subject to such tensioning, said means pivoting the deck 4comprising a rocker member, a sleeve on the deck slidable and rotatable on the rocker member, and means to bind the sleeve .against the rocker member.

4. A machine of the class described having a deck, sawing mechanism carried by the deck, a frame, means pivotally connecting the deck to the frame, cushioned means carried by the frame engaging and supporting the deck on opposite sides of its pivotal axis, and brackets extending forwardly and rearwardly of the frame mounting the spring means.

5. A machine of the class described having a deck, sawing mechanism carried by the deck, a frame, vmeans pivotally connecting the deck to the frame, parts on the frame on opposite sides of the pivotal axis thereon on which the frame rests, elements mounted by said parts, and cushioned means carried by the elements engaging the under surfaces of said parts and the upper surfaces of the deck.
